Anti-reflective glazing

Despite the excellent transparency of modern glazing, the view from the bright exterior to the darker interior may be hindered by reflections, depending on the viewing angle and incidence of light.

Despite the excellent transparency of modern glazing, the view from the bright exterior to the darker interior may be hindered by reflections, depending on the viewing angle and incidence of light. Shop window glazing in particular can diminish the view of items behind the glass due to reflections. 

Anti-reflective glazing

A standard float glass surface reflects approximately 4 % of visible light. This means a float pane with two surfaces reflects 8 % and a double glazing close to 16 %.

Special anti-reflective coatings, such as GUARDIAN Clarity™,  are able to decrease the reflectivity significantly. The coating on both glass surfaces reduces the degree of reflection on glazing with one pane to less than 1 %. 

Anti-reflective coating Guardian Clarity

For highest requirements on reducing reflections, all surfaces of a desired glass build up should be anti-reflective coated. Any uncoated float glass surface would increase the visible light reflection by 4 %.


Clarity™ anti-reflective coating is applied on UltraClear low-iron glass as a standard and is available as single and double side coated. It is heat treatable to fully tempered or heat strengthened glass and can be bent using the gravity or tempering technique (→chapter 8.4).

Guardian Clarity is particularly suitable for:

  • Retail storefronts.
  • Display cases in shops and museums.
  • Protection of paintings and other artwork in art galleries.
  • Control rooms.
  • Architectural entrances.
  • Airports/control towers.
  • Stadia/Arenas.
  • Petrol Stations    .    
  • Car showrooms.
  • Hotel Lobbies.
  • Restaurants.
  • Rooftop bars.
